On Soulver, a visual approach to calculating figures

Initially, I balked at spending so much cash for a calculator — what kind of fancy calculation was I ever going to do!? — but was quickly sold on it by Chris, who showed me how he used it to make estimates.

That was more than five years ago, and since then we’ve picked up the habit of storing the Soulver file as supplementary documentation alongside our proposals, so that the internal calculations can be traced later on.

Soulver lets me play around with numbers without losing track of what I was trying. I tend to use it to calculate costs and resource projections (fun!) and always take a moment to appreciate the ingenuity of this approach 🙂
